Powerbi Query

Hello.

 

I am using an invoked function to get my data. However if the table generated is empty, the next steps causes an error to my dashboard. I want to create a step where if this step results to an empty table, a new table with same column names and blank row values will be created to avoid errors.

    Hi Anonymous ,

     

    Use a if statement with a Table.IsEmpty something similar to:

     

     

    if  Table.IsEmpty ( YOUR EXPRESSION)  = true then ALTERNATIVE EXPRESSION else YOUR EXPRESSION

    Hi Anonymous ,

    Based on the description, open the advanced editor and try to add the following formula.

     

    let
    Source = YourFunction(),
    IsEmpty = Table.IsEmpty(Source),
    Result = if IsEmpty then
        Table.FromRecords({[name= null, number = null]})
    else
        Source
in
    Result

     

     

    Best Regards,
